[specific embodiment]
The utility model is described in further detail below by specific embodiment combination attached drawing, so as to more preferably
Ground understands the advantages of the embodiment of the utility model and its various aspects.Below in an example, embodiment party in detail below is provided
The purpose of formula is easy for becoming apparent from the content of the utility model thorough explanation, rather than limitations of the present invention.
Such as Fig. 1, the utility model provides a kind of loudspeaker 10 comprising frame 15 and is contained in the frame 15
Vibrational system V and magnetic circuit system M.Wherein, vibrational system V includes vibrating diaphragm 11 and the voice coil for driving 11 vibration sounding of vibrating diaphragm
12.The voice coil 12 is connected with external circuit.The magnetic circuit system M includes magnetic bowl 14 and the magnetic that is fixed on the magnetic bowl 14
Steel 13.
As shown in Fig. 2, vibrating diaphragm 11 includes centrally located top dome portion 11, is arranged on the outside of the top dome portion 11
Ring portion 12 and the fixed part 13 extended from the outside of the ring portion 12.
Please refer to Fig. 2 and Fig. 3, the shape in the ring portion 112 is round rectangle in the present embodiment comprising two
A long axis being oppositely arranged in 114, two short axles being oppositely arranged 117 and the adjacent long axis of connection while and turning when short axle
Corner 116.
Wherein, the long axis at 114 and the short axle 117 on be additionally provided with forked reinforcing rib 115, it is described forked plus
